Mine would be about Hiccup and Valhallarama...Like maybe its the anniversary of her death and Hiccup's kinda backing off from everyone so Astrid and the others try to cheer Hiccup up and end up failing comically.

That'd be sooo cool like maybe he could tell the story of how she died and there'd be flash backs from when Hiccup was growing up and show how Val took care of him.
